OF HENDERSON, NEW ZEALANB.

'srnAYrNe APPARATUS. y

To aZZ 107mm t may concern.'

Be it known that I, BENJAMEN FRANKLIN CRANWELL, a citizen of the Dominion of New Zealand, and residing at Henderson, in the Provincial District of Auckland, in the Dominion of New Zealand, have invented certain new and useful improvements in Spray ing Apparatus, of which the following is a specification.

The invention relates to spraying appain a portable tank and the spraying is effected by a motor driven spray pump.

The invention has for an object to provide an ellicient device of this character mounted upon hollow Wheels designed to act as a. reservoir for the spraying liquid, suitable means being carried upon the frame- Work of the devicefor withdrawing, as desired, the liquid from the reservoirs and diffusing it upon the ground or objects to be treated.

Other and further objects' and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

rl`he invention is illustrated in the drawing Wherein1- Figure 1, is an end perspective elevation, Fig. 2, a vertical sectional elevation of one of the drum Wheels. F ig. 3 is a diagrammatic view showing the pump mechanism.'

The drawing illustrates the employment Referring first to Fig. 1:--The Wheels 1 and 2 are in the form of hollow drums adapted to contain a spraying fluid, and support ing a frame 3, upon Which is mounted an oil motor e adapted to drive aspray pump 5" through the spur gearing 6. A pair of shafts 7 is connected to the frame for transport pur oses. v

T e construction of the drum Wheels is illustrated in Fig. 2, and as both 'drum Wheels are precisely similar, it isonly necessary to describe one of them. YThe drum Wheel 2 has the journals 8 and 9, one upon each side, which are respectively carried in The suction pipe 12 from the pump passes through the journal S, which is provided with a stuiling box 13, and a right anale tension pipe ilitherefrom is provide with a rose strainer 15 at is end which is located Specification of Letters latent.y

near the bottonfof the .drum wheel.

' Patented May 5, i914. serial no. 632,911.

The return delivery pipe 16 from the pump (to conduct the spraying fluid back to 'the drum when spraying lhas been temporarily discontinued) is connected to a hollow s indle 17 Which passes through the journa 9, and is provided IWith a spigot 18 through which the fluid is emitted.

A relief valve 16?L permits the spraying fluid to be returned to the drum Wheel when the pressure of liquid from the pump, en ceeds a predetermined limit( The end of spindle 17 is journaled in a cup bearing 19 upon the end of the pipe 12, and has fixed upon it a sprocket Wheel 20 connected With a' sprocket pinion 21 by a sprocket chain 22 having a series of agitating paddles 23. The sprocket pinion 21 is journaled upon an arm 2e projecting from the extension pipe 1li.

A series of buckets 25 is secured to the inner Wall of the drum Wheel, and they are designed to raise a certain quantity of the sprayino iiuid during the revolution of the drum Wlieel for the purpose of further mixing and agitating the fluid.

A canvas ring or tread piece 26 around the circumference of the Wheel drum is desiged toV minimize wear in traveling over rough surfaces.

The hollow spindle 17 is revolved by a sprocket Wheel 27 fixed upon it and connected by a sprocket chain 28 with a driving sprocket pinion 29 upon a shaft-30, Which is rotated by chain and sprocket gearing from the motor.

The spraying fluid is supplied to the drum through a screw filling plug 40. This plug is sufficiently large to give access-to, the bolts 41 which secure the journalsito the drum Wheel, and, to the rose strainer and other parts Within it.

Referring again to Fig. 1, the suction pipes 12 leading from the respective drum.

Wheels are connected to the -pump 5 and the,

delivery pipe 31 is provided intermediate its ico ends with a fitting 32. Leading from the` lateral branches of this fitting are pipes respectively controlled by taps 33 and 3d and adapted to receive the rubber or other pipes leading to the spraying nozzles. The' end of the pipe 31 is connected to creen-- pipe 35, the respective ends of which connected to the return de* e: the respective drums. end cf pipe 31 regal liquidto the pipe 35 and tl taps may, one or other of them., be ein. s., .n
